2008-07-14tipc: Optimization to multicast name lookup algorithmAllan Stephens
This patch simplifies and speeds up TIPC's algorithm for identifying on-node and off-node destinations that overlap a multicast name sequence range. Rather than traversing the list of all known name publications within the cluster, it now traverses the (potentially much shorter) list of name publications made by the node itself, and determines if any off-node destinations exist by comparing the sizes of the two lists. (Since the node list must be a subset of the cluster list, a difference in sizes means that at least one off-node destination must exist.)

2008-07-14tipc: Fix bug in scope checking for multicast messagesAllan Stephens
This patch ensures that TIPC's multicast message name lookup algorithm does individualized scope checking for each published name it examines. Previously, scope checking was only done for the first name in a name table publication list, which could result in incoming multicast messages being delivered to ports publishing names with "node" scope, or not being delivered to ports publishing names with "cluster" or "zone" scope.

2008-06-04tipc: Add missing spinlock in name table display codeAllan Stephens
This patch ensures that the display code that traverses the publication lists belonging to a name table entry take its associated spinlock, to protect against a possible change to one of its "head of list" pointers caused by a simultaneous name table lookup operation by another thread of control.

2008-06-04tipc: Prevent display of name table types with no publicationsAllan Stephens

2008-05-12tipc: Enhancements to name table initializationAllan Stephens
This patch enhances the initialization of TIPC's name table by removing a pointless spinlock operation, and by using kcalloc() to detect requests for an oversized name table. Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>

locking init cleanups: - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK() - convert rwlocks in a similar manner this patch was generated automatically.

2006-03-20[TIPC]: Remove inlines from *.cSam Ravnborg
With reference to latest discussions on linux-kernel with respect to inline here is a patch for tipc to remove all inlines as used in the .c files. See also chapter 14 in Documentation/CodingStyle. Before: text data bss dec hex filename 102990 5292 1752 110034 1add2 tipc.o Now: text data bss dec hex filename 101190 5292 1752 108234 1a6ca tipc.o This is a nice text size reduction which will improve icache usage. In some cases bigger (> 4 lines) functions where declared inline and used in many places, they are most probarly no longer inlined by gcc resulting in the size reduction. There are several one liners that no longer are declared inline, but gcc should inline these just fine without the inline hint. With this patch applied one warning is added about an unused static function - that was hidded by utilising inline before. The function in question were kept so this patch is solely a inline removal patch.
